St Kilda has re-signed young defenders Daniel McKenzie and Brandon White for a further two seasons, tying the pair to the club until at least the end of 2019.

McKenzie, who was taken at pick No. 22 in the 2014 National Draft, has played 16 games in his first two seasons at Linen House Centre, including seven of the final eight games last year where he found a home at half-back.
